+<h2>DESCRIPTION
+<a name="DESCRIPTION"></a>
+</h2>
+
+
+
+<p style="margin-left:11%; margin-top: 1em"><b><i>TIFFGetField</i></b>
+returns the value of a tag or pseudo-tag associated with the
+the current directory of the opened <small>TIFF</small> file
+<i>tif</i>. (A <i>pseudo-tag</i> is a parameter that is used
+to control the operation of the <small>TIFF</small> library
+but whose value is not read or written to the underlying
+file.) The file must have been previously opened with
+<i>TIFFOpen</i>(3TIFF). The tag is identified by <i>tag</i>,
+one of the values defined in the include file <b>tiff.h</b>
+(see also the table below). The type and number of values
+returned is dependent on the tag being requested. The
+programming interface uses a variable argument list as
+prescribed by the <i>stdarg</i>(3) interface. The returned
+values should only be interpreted if <i>TIFFGetField</i>
+returns 1.</p>
+
+
+<p style="margin-left:11%; margin-top: 1em"><i>TIFFVGetField</i>
+is functionally equivalent to <i>TIFFGetField</i> except
+that it takes a pointer to a variable argument list.
+<i>TIFFVGetField</i> is useful for layering interfaces on
+top of the functionality provided by
+<i>TIFFGetField</i>.</p>
+
+
+<p style="margin-left:11%; margin-top: 1em"><i>TIFFGetFieldDefaulted</i>
+and <i>TIFFVGetFieldDefaulted</i> are identical to
+<i>TIFFGetField</i> and <i>TIFFVGetField</i>, except that if
+a tag is not defined in the current directory and it has a
+default value, then the default value is returned.</p>
+
+<p style="margin-left:11%; margin-top: 1em">The tags
+understood by <i>libtiff(3TIFF),</i> the number of parameter
+values, and the types for the returned values are shown
+below. The data types are specified as in C and correspond
+to the types used to specify tag values to
+<i>TIFFSetField</i>(3TIFF). Remember that
+<i>TIFFGetField</i> returns parameter values, so all the
+listed data types are pointers to storage where values
+should be returned. Consult the <small>TIFF</small>
+specification (or relevant industry specification) for
+information on the meaning of each tag and their possible
+values.</p>
